|IMO you should your impeller every season and inspect the impeller housing while your at it. |
The housing is made out of plastic on most boats and it doesn't take much to score it.
How many hours/seasons on that one?
|That came off a boat I just bought and I believe it has 180 hours on it.|
|I think I am going with the every other year schedule. I only put on 50 hours a season. The Merc V drives are a PITA to change so no since over doing it.|
|I'm sure your safe with only 50 hours and no dry starts. I'm told that a impeller can go a few hundred hours most of the time but I figure that it's so cheap to change I'll do it every year. |
I'd hate to ruin a weekend over a cheap part that I could of replaced at the beginning of the year.
|not a bad idea to keep a spare in your boat or your tool box just in case... the guy i got my last boat from always kept a spare in it.. not a bad idea.. could really save a weekend!!|
A spare prop too.
Most of the time when I pull the impeller I can see some sort of wear on it. (cracks or torn fins)
|where exactly would it be located?funny thing is i have a spare but not really an idea of where to change it out |
It's a small pain in the ass on a V-drive. Follow the belt that goes around your alternator and water pump and you will find it.
|roger that....thank you sir|
|Here is blow up of the waterpump/impeller for my Sanger. |
| Biggest problem is when a boats sits long periods of time, they dry out and then when you take the boat out they fall apart.|
You will need to unbolt the waterpump bracket which is # 12 on the drawing and remove entire pump assembly. Once out the impeller should be cake.
|You might have to remove the gas/water separator too just to get it out of the way.|
|I think next year I am going to step up and buy one of those all-brass replacement pumps from Skidim.com and eliminate this rubber impeller/plastic pump housing deal from my life completely. Removing the source of a potential problem and a maint. PIA will be worth the 2 or 3 hundred bucks the thing costs. |
|Walt, that's "nice." I changed mine not long ago, and every singe blade had at least a small amount missing. The housing was in great shape though. I replaced it anyway, since I bought the kit. May as well use it. |
$289 at Overtons. I was thinking about getting it... Didn't. We'll see if it was a good choice.
|Discount Inboard Marine has it for $244.99 |
They state it is only for V-Belt applications tho, which leaves me out...
|Wow you guys are really letting some hours mount before you change your impellers. |
I have been changing mine every 50 hours along with my oil and tranny fluid.
I keep an extra in the boat and another in my truck plus tools to do the change.
|The brass housing sounds like a great idea but I wonder if it prolongs impeller life ?|
|I doubt it. The impeller can get hosed for all kinds of reasons. My I/O didn't have it changed for about 8 years. I finally did, and it looked brand new. ?????? I guess it just depends. |
The thing about the brass is that you will not have to replace the housing. Just pop the impeller out, swap with a new one, and put it back together.
